Establishment of relationships between native and inhalation device specific spirometric parameters as a step towards patient tailored inhalation device selection

IntroductionDrug emission from DPIs is dependent on the inspiratory flow parameters through them, which are not directly measured by standard spirometry. Their estimation based on native spirometric data could help in choosing the appropriate device and optimizing the drug deposition.ObjectivesThe aim of this study was to survey patient preferences and to find correlations between breathing parameters of COPD patients through DPI devices and...
